If the isolation value between tap and output ports is higher, what is the benefit?

The higher the isolation value between the tap and output ports, the more effective the system is at reducing crosstalk between those ports. This means that signals transmitted through the tap port are less likely to interfere with signals on the output port, which is essential for maintaining signal integrity. When crosstalk is minimized, the clarity and quality of the signals are enhanced, leading to better performance in communication systems.

In contexts such as fiber optics or RF applications, high isolation allows for clearer separation of signals, reducing the risk of unintended interference. This ensures that each output port can operate efficiently without being affected by adjacent signals, thereby improving the overall reliability of the system.
